Android禁用下拉框

framework\base\packages\SystemUI\src\com\android\systemui\statusbar\phone\PanelView.java

    private void trackMovement(MotionEvent event) {
        // Add movement to velocity tracker using raw screen X and Y coordinates instead
        // of window coordinates because the window frame may be moving at the same time.
        float deltaX = event.getRawX() - event.getX();
        float deltaY = event.getRawY() - event.getY();
        event.offsetLocation(deltaX, deltaY);
        if (mVelocityTracker != null) mVelocityTracker.addMovement(event);
        event.offsetLocation(-deltaX, -deltaY);
    }

    public void setTouchDisabled(boolean disabled) {
		if(YlDefineSystemProperties.YL_MMI_BOOL_DEL_DROPDOWN_BOX){
			mTouchDisabled = true; //add by lwz 
		}else{
			 mTouchDisabled = disabled;
			}       
    }

主要是setTouchDisabled方法里面去设置为true，其次是默认的。
